Be it known that L, dzmrir liraus, a citizen oi VlPoland, residing atChicopee Falls, county of Hampden, and'S-tate ot 'lvlassachusetta haveinvented certain new and useful improvements in Steel-Cutting Machines,of which the following is a specication. n This invention relates toimprovements in steel cutting devices, particularly adapted for cuttingat one time a steel plate, bar, rail or the like into a plurality ofparts of equal lengths. y Y j lt is the principal object ot theinvention to provide a device oi thischaracter which is adjustable forthe cuizting of steel or likev articles of diierent widths.

Another object ot the invention is the pro visionl of a machine oiz thistype which is easilyl operated by motor or other power,` and which issimple and inexpensive, however reliable, durable and efticientl,

vwhich a shaft 11 is journaled for a disc 12,

Other objects and advantages or" my invention will become more Jfullyapparent yas the descriptionV thereof proceeds by the inf spection ofthe vaccompanying drawings, forming a materialA part of this disclosure,and in which Figure 1 shows a machine constructed according to thepresent invention rin side ele'- vation. l

A table 10 carries projections 9 between detail view of and for thepulley or belt wheel 13, laterally disposed tosaid disc, over which abeltA 14: is guided which is driven by a pulley V15 on a shaft 16 or' amotor or' other driving machinery. y To a projection of the bottom bar17 of the table 10, a link 18 Vis pivotally' secured at its lower end,the upper endotwhich carries a. head 19, adapted to slide back andJforth upon rods 2O supported in the table 10 and a leg 21 of the same.Y The upper end of kthe link 1S is slotted as at 22, and a pin 23 of thehead is adapted to execute a limited verticalv movement in said slot.
